The new 250R is the first production quarter-liter motocrosser to be delivered with EFI, and it's a wonderful thing. The Honda PFM-FI (Programmed Fuel Management Fuel Injection) works flawlessly, metering fuel through the Keihin 50mm throttle body for smooth, precise throttle response. The bike barks, yips, growls and purrs at your command-just wiggle your throttle hand and listen. It's immediate, predictable, functional and fun. It's more efficient, too: With the perfect air/fuel ratio provided at all times, no fuel is wasted, so the new 250R can run just as long in spite of its gas tank measuring .4 of a gallon smaller than last year.
